AudioQuest Forest 3.0m (10 ft.) Black/Green HDMI Cable Forest's solid Long-Grain Copper allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance Solid High-Density Polyethylene Insulation ensures critical signal-pair geometry while minimizing insulation-induced phase distortion This means that all AudioQuest cables up to 10 meters are capable of transmitting 100% of the data required for all of HDMI's current audio/video features including multichannel high-resolution audio, 1080p and 4k video, and 3D video from Blu-ray All signal conductors controlled for digital-audio direction in AudioQuest HDMI cables, and care is even taken to run the conductors used in the Audio Return Channel in the opposite direction to ensure the best performance for that application
